Saidfbarsare held Lin. -rspacedI-'elationto each other and rthe shoe 'elements:by-spacing.washers-241y VEach of the levelling spuds is of like construction las are fthe parts associated therewith, hence a descriptionf of one lWill suiiicefor both.

r Theseparateelements 21 extend-upwardly and are designed to'be clamped in'their adf justed positlons through the operation of a fmanua'lly controlledfbraking mechanism.

To /thisaiend 'there is mounted {upon the elef Lments iflfandffaboxdkecasting 25-(see more .particularly'aFigures'3 :and 4 ),..said .lcasting 100y i i having a rectangular opening extending upwardly therethrough (see the right hand end of Figure 3) and overlying the upper end thereof is a plate-'like member 26 having upstanding elements 27 which form the support for pins 28 and 29 upon which rollers 30 and 31, respectively, are mounted. A second pair of rollers 30EL and 31a (Figure 2) is mounted Aat thelower end of the casting and together `with the upper rollers serve. to guidelthe t members 21 intheir up and down movement. Said member 26 is positioned upon the upper end of the box-like member 25 by pins 32 and the parts are heldin placebyl a series of hook bolts 33, the lower end of which underlieV bars 84 interposed between the hooked ends and theupper inwardly extending flanges of the railmembers 4 and 5.i When the nuts 35 are 'screwed down, the parts are securely locked infplaceV and held against movement with reference to the cross rails 4 and 5.

Interposed betweenv the various elements 21 the rear wall 36 ofy the box-likemember and the orwardfadjustable compression plate 37` is a series of kfriction plates. Said plates `will preferably be formed of metal elements 89 having .secured on opposite sides thereof friction sheetmaterial 40. Said sheet material 40 isfsomewhat narrower than the Width of the plate 139 but slightly greater than the width of the elements 21. The lower endsof saidmembers 39 rest uponA a wear plate 41 located in the lowerportion of the box, there being a second wear -p1ate42 located beneath the plate 41. A. wear plate 43 is located at the vupper end of the boxand overlies the pressure producing plate 37, said plate also resting at its lower end upon thewear plate41.

Securedfinl an opening formed in the wall 44 yof the box-like member 25 is a screw threaded bushing 45 in whichis mounted a quick pitch .screw 46`the inner end of which takes against the bearing block 47 mounted in a V.recess VJformed in the adjacent face of the pressure element37.y

A hand lever 48 is attached to the outer end of the screw 46 vand 3 by .manipulating the handle, pressure may be exerted upon the plate 37 and throughr it upon the various elements 21 and the interposed friction braking plates. Reverse movement of the handle, of course, relieves the pressure and allows the c levellingspud or the elements 21 thereof to pass freely through the friction lplates either in an upward or downward direction, as'the case may be. Y

A stop arm 49 is secured in place beneath one of the bolts 35 to limit the outward movement of the lever 48 or when the lever is in that position where the parts are Jfreedof `trictional contact.

*Iny operationthe car Vis run along the rails to a point where it is desired Yto elevate 'the track. Clamps are then brought into locking relation or engagement with the rails.

The shoe 18 is, of course, at such times in its elevated position but when the car has ybeen secured to the rails the centerspud 12 is lowered yand the levelling spuds are allowed to pass freely in a downward direction, the leversv48 being at such times thrown outwardly to the release position.

When the shoe 18 has been positioned power may be applied through the shaft 7 to the spud 12 whichr will cause the car to be moved upwardly carrying with it the rails and the attached ties.

When the track has been brought to the desired elevation, power will be cut oliE from the driving mechanism and the levers 48 thrown `inwardly tothe locked position, it

being understood, vof course, and as will be apparent upon 'inspection kof Figure '3, that the screws 46 arereversedV or `'one isright handed and the other is left handed.`

Y When the desired yelevation is had either in :parallelism nto the road bed orV atan angle thereto, the operator may maintain such position byy manipulating the handles 48 to lock the braking mechanism and at the same time Vwill release the power connection which is operative in relation to the spud 12.

- It is to be noted that the levelling spudsj105 take the strain incompression; that they are rugged and will carry a considerable load,

vconsequently they are advantageous over a structure wherein'cables are employed to prevent tilting of the car with reference lto the center spud or boom.
